TO ALL WHOM IT MAY CONCERN:

'Be it known that I, WILLIAM R. W'ALDRON, of the town ot' Webster, in the county of Washtenaw, State of Michigan, have invented a new and useful machine for unloading hay, to be called Wa-ldrons Hay Unloaderg" und I do declare that the following is a full, clear, and exact description of thesame, reference being had to the annexed drawings, making n. part of this specification.

The object of this device is to unload hay from a wagon and raise it on te a. stack, or to unload from the outside of` a barn and deposit it on the inside.

To construct it, take three poles, A A A', so long that when they are placed in position for usc, as shown in the figure, there will be room for the stack within and under them- Place the lower ends o? the poles A A where they will be when raised in position, and bring the top ends together. Then place the top end of A between them, and letl it extend back from the others. While it lies in this position fasten them together by meansof the bolt or pin, D, and secure the pulley'E. To put it in position for use raise the poles at D and push up on the pins C and I". The lower end of A is embedded a foot or two in the ground,` and has a pin or round,f, passing through it a short distance above the ground. The inclined stakes, G G, are driven into the ground, so as to hold down the pin F. This forms a cheap and safe anchorage for the whole device. Three other poles, B B B', arranged and anchored in the same way, are placed directly oppositethe former, and far enough from them to allow of the free passage of the load between thcin. The poles Aiand B', which are. anchored, should stand opposite the load. The poles B B B' may be shorter than the others.l One end ol thel rope I is attached to the head of the fork at a, thence it passes around the pulley E, thence under the pulley K, which is attached to the head of the fork, thence over the pulley E', thence under the pulley H, and thence to the whillc-trec, to which the horse or other power is attached. I

To work the machine any ordinary horse-fork may be used and attached as above described. When the fork is loa-ded and the horse draws on the rope, thc fork with its load will, at first', be raised nearly vertical, but afterwards will be drawn gradually towards E, and when K arrives nchr E it will be over the centro of the .stack and the fork is tipped. The resistance of the air during the descent ot' thc hay causes it to strike lightly upon the stack, and is in a position to be easily moved by the stack-maker. The reverso movente-nt of the horse causes the fork to return to its former position, ready to repent the operation. To remove thedeviee the lower ends of A and B are carried directly away fronrthc stuck, thus drawing the tops of the other poles over until all are brought top-the ground. For unloading in a burn the pulley E can be fastened within the burn, hence only one set of poles willbe needed.

Vilhat I claim as lny invention, and desire to secure by'Lctters Patent., is- The combination ot' the polos, pulleys, rope and anchorage, when arranged substantially as herein described, and for the purposes herein set forth.
